Designed by Woolworth Building architect Cass Gilbert and opened in 1919, the 95-acre Brooklyn Army Terminal in Sunset Park was one of the largest concrete structures in the world. The complex opened at the conclusion of World War I and used for various purposes over the years including a military prison and storage space for alcohol and drugs during Prohibition. During World War II it was the largest military supply base in the country. Today the site is on the National Register of Historic Places and houses a diverse group of local industrial businesses managed by the NYC Economic Development Corporation.
